I purchased Acer Nitro 5 (Nitro AN515-42; Part Number: NH.Q3RSI.006 which has RX 560X graphics card) 2 months ago and since today morning i get flickering pixels when i start game (i have only fortnite installed). This started after i upgraded to 1903. In normal mode all applications work fine but as soon as i start a game, notice random flickering pixels in multi-colors, some big and bright whereas others are small. Connected to TV and see the same flickering pixels there as well. Along with the flickering pixels, there is occasional white boxes that appear randomly, and visible ghosting effect of trees.
I have tried following
1. Install latest Windows 1903, with latest drivers adrenalin-2019-edition-19.5.2-may22
2. Install Windows 1809 with keep nothing option and installed latest drivers
3. Clean install Windows 1809 with driver from ACER website (VGA_AMD_17.40.6001.3304_W10x64)
Any recommendations /fixes ?
